The story of the son of a carter. His father was a heretic, but while playing with a Buddhist lad, he had learnt to say “Homage to the Enlightened One (Namo arahantāna).” One day he went with his father on a journey, and as his father got locked into the city at sunset, he had to spend the night all alone under the cart outside the walls of Rājagaha. During the night, two yakkhas tried to eat him, but he uttered “Namo arahantā” and was saved. The king, hearing the story, repeated it to the Buddha. DhA.iii.455 ﬀ.
